I'm not sure the stated increased probability to drop from Katagawa Ball is correct. --Improv (talk) 22:51, December 28, 2019 (UTC)

I farmed Killavolt for 3 hours tonight - no Brainstormer. I think this drop has been moved to Katagawa ball only. Got plenty of other 'world' legendary drops and eventually a Transformer Shield (which I think is supposed to be his new dedicated drop post Nov patch based on other website sources).

Brainstormer is the Katagawa Ball's dedicated drop but can be had from the other world drops as well, including the Golden Chest onboard Sanctuary III. --SirFoggy (talk) 20:56, February 1, 2020 (UTC)
